SPECIFICATION forming part of Letters Patent No. 354,156, dated December 14,1886.

Serial No. 195,412. (No model.)

T0 all whom it may concern.-

Be it known that I,`W1LLL\M LOEFFLERg of Sheboygan, in the county of Sheboygan, and in the State of "Wisconsin, have invented certain new and useful Improvements in Lubricators for Loose Pulleys, and I do hereby declare that the following is a full, clear, and eX- act description thereof.

My invention relates to lubricators for loose pulleys 5 and it consists in certain peculiarities of construction, as will be fully described hereinafterwith reference to the accompanying drawings, in Which- Figure l represents avertical transverse section of my invention in operative position; Fig. 2, a vertical longitudinal section ot' the same; and Figs. 3 and 4 are detail sectional views showing induction-ports for the lubricant.

Referring by letter to the drawings, my pulley is represented as composed of two detachably-united sections, A B, so constructed that when `joined together their interior faces form a chamber, C.

The section A has its rim provided with an annular recess, a, that receives a correspond ing tongue, b, formed ldy cutting` away the adjacent rim c of the section B, thereby securing a tightjoint when the parts are united. The central portion, D, of the section A forms the bushing for a shaft, E, and has its free end screw-threaded, as shown at d.

The outer wall of the section B is provided with a central opening of a diameter equal to that of the bushing D, and the circumference of this opening is screw-threaded,as shown at e, to engage the threads on said bushing, this construction serving to firmly retain both sections in operative relation.

Badiating from the rim c of thesection B are a series of spokes,F,that support the main rim G, said section, spokes, and latter rim being preferably of integral construction, as illustrated by Fig. l. The rim c ofthe section B is provided with a screw-threaded opening to receive a corresponding-formed tube, f, that extends to nearly the depth of the chamber C, and the outer wall of this hub-section is bored out to form a passage, g, leading to said chamber, the entrance thereto being near the shaftbushing D. rIhe tubef and passage g serve as ports for the introduction of lubricant to the chamber O, eitller or both of said ports being employed, as may be found desirable.

The bushing D is formed with a suitable orifice, 7i, adapted to receive the united ends t' of a con tinnous strip of wicking, H, that is contained within the chamber O. is in the form of a circle,with its ends turned in so as to enter the orifice in the bushing and come in direct cont-act with the shaft E, the diameter ofthe circle formed by said wicking when first placed in position being equal to nearly that of its inclosing-chainber.

ThewickingH isheldout away from thebushing D by means of a spring, I, having inverted bow-shaped part @designed to rest upon said bushing opposite the orifice therein. The ends m of the spring are pointed,so as to be inserted in the united ends t' of the wicking H, these terminals of said spring having usually an angular bend or shoulder, a, that serves to bear against the latter substance. The contracting force of the spring I compensates for the wear ofthe wicking ends t' by the revolution of the shaft E, and acts to keep said parts always in direct contact.

In the operation of my invcntion,the spring I and wicking H being placed in position with relation to the bushing D, the pulleysections A B are united, as above described, to form the chamber'G, that incloses said wicking. Oil or other lubricant is now introduced through either or both the ports f g to the chamber C, the amount being sufficiently limited so as to prevent overflow from these induction-ports as the pulley revolves. The wicking H absorbs the lubricant in the chamber O, and delivers it to the shaft 13,011 which the pulley operates, a fresh supply of this lubricant being from time to time introduced in said chamber to keep the wicking always saturated. As the revolution of shaft wears away the ends t' of the wicking, the contracting force of the spring I toward the shaft-bushing D forces these wicking ends up in the orifice h of said bushing, to thus keep them in operative p0- sition.

I have described the wicking as one continuous strip bent in the form of a circle, and having its ends united and inserted in the oriiice of the shaftbushing, such arrangement being preferable; but I may employ two pieces or double the single piece at some point along This wicking IOO 4 wicking in operative posi/tion, as set forth.

2. A loose pulley consisting of two detachablyunited sections so constructed that when joined together their interior faces form a continuous lubricant-chamber, and oneof saidsections having its central portion in the form of a shaftbushing provided with an orifice, in combination with a wicking located in the lubricantchamber, and arranged to extend through the oricein the bushing and come in contact with the shaft to which the pulley may be connected, as set forth.

ably-united sections so constructed that when joined together .their interior faces form a continuouslubricant-chamber, one of said sections having its central portion in the form of a shaftbushing provided with an orifice, and the other section provided with an induction port or ports leading to the lubricant-chamber, in combination with a wickinglocated in said chamber, and arranged to extend through the orifice in the bushing and come in contact with the shaft to which said pulley may be connected, as set fort-h.

4. A loose pulley havlng a lubricant-chamber surrounding the shaft-bushing, in combi-` nation with a continuous strip of wicking lo- 4o cated in the chamber and bent in the form of a circle, withl its ends turned in and passed through an orifice in said shaft-bushing, and a suitable spring interposed between the lat,-

ter parts, with its ends inserted in those of 45 said wicking, as set forth.

Y 5. A loose pulley having a lubricant-chamber, in combination with a continuous strip of wicking located in the chamber and 4bent in the form of a circle, with its ends turnedin and 5o passed through an orifice in the shaft-bushing, and a continuous spring interposed lbetween these latter parts, and having pointed and shouldered ends inserted in the ends of said wicking, as setforth.

In testimony that I claim the foregoing I have hereunto set my hand, at Sheboygan, in

the county of Sheboygan and State of Wisconsin, in the presence of two witnesses.
